IMPROVEMENT IN TOOLS FOR MAKING BUCKLES.

Specification forming part of Letters Patent No. 4|,6 [0, dated February16, 1864.

.To all whom it may concern.- I

Be it known that I, ROBERT DURNING, of Lawrenceville, in the county ofAllegheny and State of Pennsylvania, have invented a new and" usefulImprovement in the Manner of Constructing Buckles; and I dohereby deelare that the following is a full, clear, and exact description of thesame, reference bedug had to the accompanying drawings, makand areemployed for harnesses and for simi-. lar purposes.

The invention consists in the employment or use of certainmeans or toolsthat may be used separately by hand, or so arranged as to be operated bymechanical means with any suitable power, and so constructed as torespectively open the end of the tongue and close the same on the bar ofthe buckle to form the tubular friction-roller and to adjust the same onthe roller-bar of the buckle, as hereinafter fully set forth, wherebybuckles of the class specified may be manufactured much cheaper than atpresent and in a superior manner.

, To enable those skilled in the art to fully understand and constructbuckles according to my invention, Iwill proceed to describe it. A, Fig.1, represents atool composed of two jaws, a. b, the shanks of whichcross each other and are connected by a pivot, c, the shank of the lowerjaw, b, having a handle, B, attached to it, and the shank of the upperjaw having a pendent projection, O, which is grasped by a vise, thelatter firmly holding the tool-wheel in use. The upper jaw, a, has aconical pin, D, at its inner side andnear its back end, and the frontpart of said jaw is curved, as shown at d. The front end of the lowerjaw, b, is curved in a similar manner, as shown at d, and the jaw b,near its back end, has a hole, f, made. in it to receive the conical'pinD when the two jaws a b are closed, the jaw b being represented partlyin section in order to show the holef. This tool A is for the purpose ofopening the eyes g of the tongues E of the buckle after the latter areforged.

In Fig. 4 a tongue is shown with its eye g in a closed state, and itwill be seen that if the tongue be placed between the jaws a b, with itseye 9 over the holef injaw b, and thejaw b forced upward, the conicalpin D will pass through t-h'. eye and open the same, as shown in Fig. 5.This opening of the eyegol' the tongue is toenable it to be fitted onthe barh of the buckle F. When the eye is opened and fitted on said bar,the eye is closed by pressing it around the bar by means of the curvedends d d of thejaws a b.-

G, Fig. 2, is a tool composed of two jaws,

tj, connected by a pivot, is, the shank of the lower jaw having ahandle, H, attached, and the shank of the upper jaw provided with aprojection, I, to be graspedby a vise. The upper jaw, z, of this tool Gis provided at its inner side with a projection, J, of cylindrical form,which extends the whole width of sai l jaw, and in the inner surface ofthe lower jaw, 7', there is made a recess or groove, Z, whichcorresponds in form to the projection J, but

is a trifle larger. By means of this projection J and the recess orgroove l'the tubular friction-rollers are formed from a flat blank, K,(shown in Fig. 6,) the blank K being laid on the lower jaw, j overtherecess or groovel, and the lower jaw forced upward, so that theprojection J will force the blank into the recess or groove Z, as shownclearly in Fig. 2, and form the roller l.

L, Fig. 3, is atool composed of two jaws, m n, fitted on a pivot, o, andprovided, respectively, with a handle, M, and projection N,

like the other tools. The jaws m n of this tool are each provided withsemicircular recesses o to press the roller 1 around the bar h of thebuckle. Two of these recesses, of different dimensions, may be made ineach jaw to suit rollers of different diameters, and similar recesses,p, may be made for the same purpose in the outer parts of the jaws t'j.

This invention has been practically tested and found to answerremarkably well, saving much time and labor and performing the work in asuperior manner.

Having thus described my invention, what I 2 I I gmno claim as new, anddesire to secure by Letters 1211 friction-rollers,and also adjustingthem Patent, is v 011 the buckles, as herein set forth;

f'flhe employmentor use, in the manufacture 0 arness and other'similarbuckles, of a sev v I ries of tools, constructed substantially as HILiLshown, for the purpose of opening the eyes of Witnesses: the tongues ofthe buckles and closing the G.
